Up until now, ClickTale had raised only $800,000 in funding, most of it coming from early backer YL Ventures, but has managed to take on customers like T-Mobile, Booking.com, CBS, Groupon, LinkedIn, Lenovo and about 80,000 others in the past few years.

ClickTale aims to take the guesswork out of website optimization, conversion analysis and usability research by providing businesses with insights into their visitors’ entire online experience.

“We are excited to have Amadeus and Goldrock join ClickTale as we continue to create more value for our customers by helping them achieve online success. This investment will enable us to broaden our product offerings, invest in R&D and expand our operations globally.”

Yoav Leitersdorf from YL Ventures, an early investor in ClickTale, adds:

YL Ventures spent much of the last five years helping the founders of ClickTale build an outstanding company with hardly any capital.

In fact I am not aware of any other startup that has achieved this level of traction on this little funding, and such incredible progress in a SaaS model, with such extreme capital efficiency.

Founded in 2006, ClickTale says the fresh cash will be used to bankroll further product development and drive global growth.
